First, provide a good water quality environment for sea fish cage culture
1. Readjust the layout of the breeding cage
Determine the size of the culture cage based on the production plan. Through local government organizations, scientific and technical personnel elucidated the scientific rationality of the rational distribution of breeding cages, and extensively mobilized farmers to deduct 70% of the existing cages in proportion, and according to (NY/T 5061-2002) “Pollution-Free Food Cultured Large Yellow croaker "Technical Specifications" standard for re-layout.
2. Strengthen the daily protection of the environment in the cage area
(1) After two years of continuous breeding of cages in each culture area, they should be uniformly collected on baffle devices and cages and rest for 3 to 6 months.
(2) According to the shallowness and depth of the place where the cage was placed, after 4 to 5 years of breeding, the cage position can be moved in the reserved free sea area. The bottom of the original cage was cleaned up to restore the ecological environment of the sediment.
(3) Sanitary environment in the cage area: First, domestic sewage, wastes, residual baits, garbage, dead fish, and oil stains on the raft should be collected and put into ashore for harmless treatment. Second, wash cages should be washed after disinfecting inside the carts, and the flushing cages should be collected and disposed of. Third, there must be anti-oil facilities outside the fishing line.
3. Promote the ecological breeding mode of fish, shellfish and algae
Under the premise of leaving the channel between the cages and the surrounding space, seawater fish cages, shellfish, and algae cultivation zones are used in the layout. The shellfish can filter the residual bait particles and phytoplankton suspended in the water body to grow well and make the seawater clean. The algae can absorb the nitrogen and phosphorus emitted by fish and shellfish and grow well, and the oxygen produced by the algae photosynthesis , can increase the amount of dissolved oxygen in the water body, ensure the life activities of fish and shellfish, promote the oxidation of pollutants produced by fish and shellfish, and produce high-quality shellfish and alga products. In this way, a mutually beneficial and benign ecological community formed in the area of ​​the cage area will not only improve the aquaculture efficiency in the sea area, but also improve the ecological environment in the sea area.
4. Use high-quality, palatable artificial pellet feed and appropriate feeding
High-quality, palatable artificial pellet feed can improve feed utilization, reduce bait coefficient, and reduce the amount of residual baits. Instead of feeding fresh fish, high-quality buoyant artificial feed should be used to protect the aquatic resources and reduce the contamination of residual baits on cage culture areas.
Second, to provide seawater fish cage culture with excellent quality and robust seedlings
1. Seed germplasm requirements
Using the original species or selected breeders to grow fast and individual large breeds of broodstock; China Agricultural Network changes the current inbreeding due to the misuse of small individual broodstock, resulting in the miniaturization of species of marine fish culture, decline in disease resistance, and early sexual maturation Deterioration.
2. Physiological requirements of the seed
To promote low-density ecological cultivation, the total seedling size of 2 cm in fry of large yellow croaker should be controlled at 5,000 or less per cubic meter (the other types of marine fish culture should be even lower), so that no drugs or less drugs are used during the nursery stage. Fast growth, good vigor, no disease, high survival rate.
The stocking density of marine fish species raised in cages should be appropriate, and the higher the density, the better. Under the conditions of deep water in the cage area, reasonable layout, smooth water flow, and good water quality, the cultivated large yellow croaker can produce 105 kg per square meter or a yield of 15 kg per cubic meter, a survival rate of 90%, and fish species. Develop fish size specifications for fingerlings.
Third, the prevention and control of diseases
At present, the main diseases of cage culture of sea fish are caused by viral, bacterial, parasitic, predators, bait, and others. Prevention of fish diseases should be based on prevention.
1. Seed quarantine
(1) Inspection, quarantine, and prevention of pathogens should be carried out before the transfer or placement of seedlings. (2) Diseased seedlings should be treated and treated in situ, cured and killed before the infectious agent can be transported and released, and the pathogens can be cut off from the source.
2. Comprehensive measures for disease prevention and control
(1) Promote the use of fish vaccines to reduce aquaculture use. (2) purchase strong disease-resistant seed. (3) Cut off the route of transmission of pathogens: Diseases and dead fish must be treated in a non-hazardous manner and must not be thrown into the sea to prevent the spread of the disease. (4) The fish species are disinfected before they are released.
